Tommy Edison, the Blind Film Critic, has amassed a loyal YouTube following by answering viewers' questions about his life as a blind man with his trademark sense of humor and charming personality. He's more than happy to patiently respond to all the questions people are normally too tactful to ask a blind person, like "Can you draw?" and "What are your favorite things to touch?"

Now, Edison has one-upped himself by answering the most personal and inappropriate question yet, which he says is also the one he gets most often: "How do you know when to stop wiping your butt?" You know you want to know the answer.
